Cate's lucky camisole

The blonde beauty scooped the Best Supporting Actress prize for her portrayal of Katharine in 'The Aviator' and believes the pretty underwear she wore while filming brought her luck.

A source said: "Cate was wearing an undergarment lent to her by Hepburn's goddaughter, Katharine Kramer.

"The director Martin Scorsese introduced Cate and Katharine before filming as he thought she might help her prepare for the role.

"As the undergarment was a gift from Hepburn, Katharine thought it appropriate she should pass it on to Cate for good luck."

When Cate won her award at the star-studded event, she thanked the late screen beauty as well as announcing she wanted her young son to marry Martin Scorsese's daughter.

She said: "When you play someone as terrifyingly well-known as Katharine Hepburn, it's a collaborative effort - you need as much help as you can get. So thank you of course to Miss Hepburn - the longevity of her career is inspiring to everyone.

"But most importantly, on behalf of everyone I know on 'The Aviator', thank you to Martin Scorcese. I hope my son will marry your daughter."
